The shares in your brokerage account would automatically go threw the symbol change....you would buy and sell as before. I have a lot of experience with pink sheet companies.... Unfortunately all lost 98 percent of their value. While on the pink sheets, companies are free to issue more shares. One company I bought issued 700 billion shares. Others like to issues press releases while dumping shares on the public. After the stock price crashes, they do a 1 for 20000 reverse split and start again. A lot of them like to lie. They can say what they want and issue false press releases and not get into trouble, because they trade on the "pink sheets." Not saying that this will happen with ATSG, but the professionals avoid pink sheet companies. I believe mutual funds are prohibited from buying stocks on the "pink sheets." After the dust settles, and it turns out ATSG is still above water, Hete may be able to work something out (possible reverse split with assets greater than liabilities).
